   Haowei & Hanzhi · September 27, 2026
   A one-page woodland wedding site, in the visual language of our
   paper invitation: cream paper, olive-green ink, black line-art.
   =================================================================

   Layout map:
     :root tokens          — colors, type, spacing
     base + paper texture  — body, fixed grain layer
     typography helpers    — display, kicker, body, lang spans
     nav                   — sticky top bar + language toggle
     hero                  — arched title, illustration, names, date
     dividers & motifs     — SVG ornaments between sections
     sections              — details card, schedule timeline, prose, FAQ
     rsvp                  — pressed-button CTA
     footer                — sign-off
     responsive            — mobile-first; widen at >=720px
     reveal animation      — fade-in-on-scroll
